It’s not rocket science: The process of downloading an album to your computer eliminates the energy and carbon emissions required to produce and ship a CD — and for you to drive to the store and buy it.

But researchers at Stanford, Lawrence Berkeley National Laboratory, and Carnegie Mellon University, including IT energy guru Jonathan Koomey, have crunched the hard data and found that despite the added energy from downloading music via the Internet, in general, buying digital music reduces the energy and carbon dioxide emissions of delivering music by between 40 percent and 80 percent.

The findings are important, because amid the increased attention on how data centers are consuming growing amounts of energy and emitting more CO2, here’s proof that the Internet can  reduce carbon emissions via dematerialization, or replacing atoms with digital bits and decreasing the amount of physical goods created.

  1. Meanwhile back in the land of reason we’re still waiting for proof CO2 has any effect on temperature. So far, there been lots of hypothesis from those who depend on the climate change hysteria for funding. Everyone likes the idea of making a little less trash.. Why not stick to a proven reality we can all agree with for a change instead of coming off sounding like like a foil hat nut case?
